Corporate life in my 20s

This is my Story

Initially, after graduating from the Singapore Polytechnic with a diploma in Engineering, I pursued a corporate career in various multinational companies. Despite a relatively successful career in the corporate world, I felt a deep sense of discontentment. I could not handle the never-ending office politics. Working daily in the office was like going for a war. I felt the emptiness in my heart had worsened over the years, so much so, I was on anti-depressants for some time. I had finally got down on my knees and started praying for God's guidance and direction. "Surely, the Universe does not want me to be in this shit. I don't think I want to live like this anymore." I had thought.

Started practice in 1999

Soon after, I started to do a lot of research and took courses in various holistic therapies, such as, spa therapy, reflexology, aromatherapy, touch therapy, and nutrition. Despite my passion and interest in these fields, I was not prepared to give up my full-time managerial position and a good salary. Besides, I was the sole breadwinner in my family. I needed to support the physical, financial, and emotional needs of my elderly parents then. How could I give up my lucrative job? After a period of part-time work in natural therapies, my decision to finally pursue a full-time career in natural medicine occurred in a spiritual moment. I was conducting a massage training at a retreat on an organic farm in Malaysia. After three days of eating organic plant foods and being surrounded by plants and herbs, an indescribable joy sprang from within me. There felt like this spring of water refreshing my heart. The calling from plants and the awareness of God's love for me was so strong that I shed tears during the sharing session with the participants and the organizers. After this spiritual awakening, I began my relentless journey to pursue plant medicine. All good things came my way, like meeting the right teachers, guides, and helping hands. I am very thankful for them. The rest is history.

Why have I started
Leaf to Life®?

For the past twenty years, I have been recommending high-quality practitioner-grade herbal extracts and supplements or nutraceutical products for my clients to support their health conditions. They have full confidence in the health products I suggested and the professional and holistic protocols that come with them. Along the way, I realized I needed to focus on holistic health since this is one of the primary duties of a naturopath – the doctor is a teacher of health. I wanted to reach out to more people in Singapore and beyond through teaching and to make my remedies available to the public. Thus, Leaf to Life ® was created.  

Practitioner Grade Products

Although many products claimed to be GMP certified (Good Manufacturing Practice), their quality still varies because the FDA (USA) gives manufacturers wide latitude to define their own 'established specifications.' As a result, some choose to be quality leaders, while others do not.

The American Botanical Council estimated that up to 30% of herbal products sold are adulterated with cheaper substitutions with the highest incidence reported in US internet sellers.

Professional Membership /Ethics

Medicinal herbs are at risk for contamination with environmental toxins. There is no regulatory requirement to test for heavy metals in raw herbs used in your food products. Good product formulations must consider the herbs' energetic properties, their actions on the organs, the organ affinities, the potential toxicities, the right synergies between the herbs, etc. Qualified and healing-centered holistic and medical herbalists are trained to create the right and safe formulaes for long-term wellness and safety.
